Abstract: ABSTRACT A method for the estimation of pore pressure within a subterranean formation containing fluid during the drilling of a bore hole. The bore hole is drilled using a drill string consisting of a drill bit fitted to its lower end, and using drilling mud pumped from the surface through the drill string and finally evacuated. The method is characterised by, whilst the drill bit is level with the formation and whilst the drill string is being raised to the surface for a distance at least equalling the drill pipe length, a)    the monitoring of the change in value of an initial parameter such as mud level in a mud tank to detect the influx of the fluid from the formation into the bore hole; b)    the monitoring of the change in value of a second parameter such as the apparent drill string weight whereby the second parameter characterises the force applied at the surface to retrieve the drill string; c)    the correlation of the values of the first and second parameters in order to detect an increase in one of the parameters, which would correspond to an increase of the other parameter, and then the determination of the increase in value of the second parameter; and d)    the estimation of the pore pressure of the formation from the increase in value of the second parameter as determined in step c).

Title: Laser, direct-write integrated circuit production system

IPC: H01L21/027
Filed: 1991-03-08
Abstract: LASER, DIRECT-WRITE INTEGRATED    CIRCUIT PRODUCTION SYSTEM                   ABSTRACT OF THE DISCLOSURE     A laser, direct-write system for making personal-ized custom or semi-custom integrated circuits with a very fast turnaround time.   The system includes a method and apparatus for high precision scanning of a submicron laser spot.  The laser beam is scanned at the entrance of a beam expander.   The beam expander reduces the scan angle and error produced by a mechanical scanning device such as a rotating polygonal mirror.  The smaller scan angle at the output of the beam expander matches well with the projec-tion optics of a laser, direct-write semi-custom integrated circuit production  system.    The  scan  error reduction permits more accurate positioning of the focussed laser spot on the surface of the semi-custom integrated circuit.
